Exercising the code below with (f "ab") produces:
A: a
ANY: a
ANY: b
Which implies (at least to me) that - alt seems to match "a" twice once
against the lit and once against anything. Any suggestions would be
appreciated.
fnparse v: 2.2.7
clojure v: 1.2.0

(use 'name.choi.joshua.fnparse)
(defn run-p
[parser input]
(let [result (rule-match parser
#(prn "fail:" %&)
#(prn "incomplete:" %&)
{:remainder input})]
(cond (nil? result) nil
(vector? result) (apply str result)
:else (str result))))
(defn f [str]
(run-p
(rep*
(alt (semantics (lit \a) (fn [x] (println "A:" x)))
(semantics anything (fn [x] (println "ANY:" x)))))
str) )
